Description

The combined type means of transportation in left lateral system " Y " font bifurcated bridge and bifurcated tunnel

Technical field

The utility model belongs to the means of transportation that make the right-angled intersection automobile traffic unimpeded, particularly two independently Y-shaped arch bridge and two independently the bifurcated tunnel be combined into the craspedodrome motor vehicle that can make the crossroad (hereinafter to be referred as: straightgoing vehicle) and the right-hand bend motor vehicle (hereinafter to be referred as the have no road occupying facility that has a good transport and communication network of the conflict right-hand bend car).

Background technology

At present, the traffic of international and domestic usual friendship crossroad, arterial street is very crowded, often stops up, and is each metropolitan common fault of the whole world.Tracing it to its cause, is because the two road usual friendship, and on the crosspoint, two road are overlapping to have become a road, and the motor vehicles on the two road can only a shared road on node, has lost half the path resource.Add pedestrian, bicycle and motor vehicle and mix row, the result that is inevitable blocks up.In order to solve this difficult problem, people have expected widening the road surface, increase the quantity of crossing runway, but the road surface can not be widened infinitely.People have expected overpass bridge again; But in existing upright civilian bridge design scheme; Can make crossroad direct lane and right-turn lane have no road occupying the conflict the overpass bridge minimum diameter more than 120 meters, not only build the cost height, and the crossroad of the two-way six-lane in old urban area can not be built all; Make the crossroad traffic congestion of present old urban area very serious, the frequent traffic paralysis in the crossroad that has.

Chinese patent 200720043390.6 " the full unblocked overpass bridge of individual layer " discloses a kind of unimpeded combining structure associating bridge of directly striding a bridge and an annular bridge of establishing at the parting of the ways.Its shortcoming: the driver must see clearly operation sign at the parting of the ways, in case can not lane change after not seeing clearly or seeing clearly, can cause promptly advancing the traffic congestion of place, crossroad in the lane change crosspoint.This overpass bridge can not be used on the road of existing standard.

Chinese patent 200820230509.5 " direct left and right commentaries on classics interchange overpass " discloses a kind of overpass bridge; Because the claims and the manual of this patent are very unclear to the description of technical scheme; But as if structure and the defective that just can understand this screen frame shape overpass bridge with Figure of description are: one, increased unwanted height and length: in the by-path position, ground away from the crossroad, continue one section pontic after the craspedodrome bridge passes again and just be connected with ground below the right-hand bend bridge on opposite, make the overhead highly very high of upper layer bridge; Increased the total length of bridge; Make whole pontic not only high not only long but also big like this, waste bridge construction expense has been blocked civic landscape.Two, local damage causes whole the damage: after the right-hand bend bridge passes below the craspedodrome bridge of ground, right side by-path and right-hand bend bridge; Be connected with ground again after the lower bridge section of the craspedodrome bridge of ground, left side by-path flushes; Also make the overhead highly very high of upper layer bridge, increased the total length of bridge, also make whole pontics be connected to a large-scale integral bridge; Once the part of this large-scale integral bridge has geology to change, its part is damaged and just will causes whole large-scale integral bridges to damage.Three, whole bridge becomes screen frame shape area occupied too big: the global shape of overpass bridge is for there being two cornerwise screen frame shape pontics; Requiring the crossroad not have the circular minimum diameter in vacant lot of building is 115 meters; And in the two-way six-lane crossroad of old urban area; Diameter reaches 115 meters almost not having, and just the overpass bridge that provides of this Figure of description almost can not be used for two-way six-lane crossroad, old urban area.

Summary of the invention

The purpose of the utility model provides the road track that meets existing left lateral system traffic specification and arranges; Small size crossroad at two-way six-lane can be built; Two " Y " font bifurcated bridges and two " Y " font bifurcated tunnels are combined into the conflict that has no road occupying of direct lane and right-turn lane, and there is long merging track section in a plurality of tracks of leaving the crossroad and two bridges that are difficult for traffic congestion add two tunnel combined type means of transportation.

The utility model solve to intersect the design of road occupying conflict point and is: be divided into three kinds of conflict points to a plurality of conflict points of right-angled intersection plane traffic: first kind is that the right-turn lane on direct lane and opposite has the road occupying conflict; Second kind be four direct lanes be divided into two groups at the parting of the ways the central area have and intersect the road occupying conflict; The third is that the right-turn lane has the road occupying of intersection to conflict with direct lane and the right-turn lane that this right-turn lane arrives the ground by-path.

Solve first kind, there is the technical scheme of road occupying conflict the right-turn lane on direct lane and opposite: craspedodrome bridge and right-hand bend bridge on two ground by-paths of right-angled intersection opposite face are one group, and every group last bridge end all is connected with same ground by-path.Two craspedodrome bridges of keeping straight on relatively are separate; Make a craspedodrome bridge after striding across right-angled intersection; Pass under the right-hand bend bridge of " Y " font Y-shaped arch bridge on opposite through ground, solved direct lane and opposite the right-turn lane intersect collision problem.Craspedodrome tunnel and right-hand bend tunnel under two ground by-paths of another group opposite face of right-angled intersection are one group, and every group the tunnel end that advances all is connected with same ground by-path.Two craspedodrome tunnels of keeping straight on relatively are separate; Make a craspedodrome tunnel after passing right-angled intersection; Stride across above the right-hand bend tunnel in " Y " font bifurcated tunnel to ground from the opposite on the vehicle, solved craspedodrome tunnel and opposite the right-hand bend tunnel intersect collision problem.This technical scheme has solved four road occupying conflict points.

Solve second kind; Article four, direct lane be divided into two groups at the parting of the ways the central area have and intersect the technical scheme of road occupying conflict: one group of four direct lane going of intersecting are current respectively on the ground two the underground independently craspedodrome tunnel of bridges and another group of independently keeping straight on; Become multilevel traffic, solved four direct lanes traffic conflict problem of central area at the parting of the ways.This technical scheme has solved four road occupying conflict points.

Solve the third; To be the right-turn lane with the direct lane of arrival ground by-path and right-turn lane have intersects the technical scheme that road occupying conflicts: from the vehicle to the by-path of ground, right side under the earth terminal of right-hand bend bridge, on stride craspedodrome tunnel and the right-hand bend tunnel below the by-path of ground, right side; In like manner wear the craspedodrome bridge and the right-hand bend bridge of by-path top, ground, right side under the vehicle to the by-path of ground, right side on the earth terminal in right-hand bend tunnel.Solved right-turn lane and the ground by-path of arrival direct lane and right-turn lane intersect collision problem.This technical scheme has solved eight road occupying conflict points.

Like this, 16 road occupying conflict points of plane traffic cross-road have been realized multilevel traffic fully, no longer include the road occupying conflict point between the rolling stock.

The design of the new function of the utility model: take ground and space for reduce the utility model combined facility as far as possible; Traffic route fully can be identical the left turn lane of right-turn lane and this ground, right side, right-turn lane by-path; The right side of going with an ability rightabout, a left side merge bridge or tunnel, and right side, the width that turns left to merge bridge or tunnel can reduce the width on 5.0 meters right left sides than side by side two the independent right-hand bend bridges or the overall width in tunnel and left-hand bend bridge or tunnel.So; The utility model is the mode of two independent bridges without the disclosed right side of Figure of description, the left-hand rotation of Chinese patent 200820230509.5 " direct left and right commentaries on classics interchange overpass ", but becomes right-hand bend bridge or Tunnel Design the right side, left-hand rotation merging bridge or tunnel to reach the purpose that the minimizing combined facility takies ground and space.

For having geology in the pontic position, the large-scale overpass bridge of avoiding Chinese patent 200820230509.5 " direct left and right commentaries on classics interchange overpass " accompanying drawing to provide changes; To the destruction of a part of pontic and the destruction that causes whole pontic; Also avoid large-scale overpass bridge can not be used for the problem of the small-sized crossroad of two-way six-lane, old urban area; Be divided into two small-sized bifurcated in the same way " Y " font fork bridges to this large-scale overpass bridge that can not be connected; With two small-sized bifurcated in the same way " Y " font fork tunnels, on the ground with underground current respectively.And also give bicycle and pedestrian ground in the road.

The driving route that the utility model not only will solve the crossroad does not have the intersection collision problem, and also being provided at has sufficiently long merging track section on the ground level road that leaves the crossroad, solves the merging track and on bridge, only has only a point and produce the problem of traffic congestion.The through vehicles of crossroad and right-hand bend vehicle not only will accomplish not have the road occupying conflict point, will accomplish that also the through vehicles, right-hand bend vehicle, left-hand bend vehicle from the Different Ground by-path has the merging track of a plurality of merging track points section leaving on the by-path of ground, crossroad.The utility model is located at ground merging the track section; Though merge the track section is the rule that ground level road is divided; The structure content that does not belong to the utility model overpass bridge, but the structure of the utility model grade separation facility can make the ground by-path can obtain to merge the track section.And a plurality of pontics that the disclosed screen frame shape of the Figure of description overpass bridge of Chinese patent 200820230509.5 " direct left and right commentaries on classics interchange overpass " can be regarded as after leaving cross friendship center merge the track at a point; Make through vehicles, right-hand bend vehicle and left-hand bend vehicle on bridge, have only one to merge the track point; This three tracks merge track point, the very easy consequence that on bridge, blocks up that causes with one together on overpass bridge.And the utility model carries out the track merging with the merging track section that can be provided at the ground certain-length, can solve from the vehicle on the different pontics because of merging the too narrow very little traffic congestion problem that produces of track point.So; Through vehicles and right-hand bend vehicle that the utility model not only can solve each bar ground by-path of crossroad have no road occupying unimpeded; Can also solve when on a ground by-path, leaving the crossroad from the vehicle on the Different Ground by-path; Very well-to-do ground is arranged as merging the track section; The disclosed screen frame shape of the Figure of description overpass bridge of comparing Chinese patent 200820230509.5 has only a position to merge the track, and then the utility model can reduce because of merging the too narrow very little traffic congestion problem that produces of track point at double.

The design of the utility model new construction:

One, the right-hand bend bridge does not stride across bifurcated " Y " font tunnel in the same way, right side: with two bifurcated " Y " font fork bridges in the same way independently, divide prong composition grouping bridge facing each other, right-hand rotation bridge earth terminal is communicated with ground, right side by-path.From under the right-hand bend bridge to the vehicle of ground, right side by-path, stride across from ground the right side in the same way the deep-seated in bifurcated " Y " font fork tunnel put section and accomplish and turn right.This right-hand rotation bridge earth terminal can also be communicated with the left turn lane of ground, right side by-path, and the left-hand bend vehicle can be realized, be this right-hand bend bridging right, left-hand rotation combined bridge with the outside bridge floor of this bridge of turning right.

The right-hand bend tunnel does not pass right side bifurcated " Y " word jag bridge in the same way: with two bifurcated " Y " word jag tunnels in the same way independently, divide prong composition grouping facing each other tunnel, right-hand rotation tunnel earth terminal is communicated with ground, right side by-path.From on the right-hand bend tunnel to the vehicle of ground, right side by-path, from underground wear the right side in the same way the high position section of bifurcated " Y " font fork bridge accomplish and turn right.This right-hand rotation tunnel earth terminal can also be communicated with the left turn lane of ground, right side by-path, and this left-hand bend vehicle can realize with tunnel, the outside face in this tunnel of turning right, this right-hand bend tunnel become the right side, dual-purpose tunnel turns left.

Two, with two bifurcated " Y " font fork bridges in the same way independently; Divide prong composition facing each other a grouping bridge, two craspedodrome arch bridges of grouping bridge respectively with the opposite in the same way the right-hand bend bridge of bifurcated " Y " font fork bridge carry out multilevel traffic in by-path position, ground away from the crossroad.The shape of right curved bridge single file section is the arcuate structure that becomes three-dimensional decussate texture central area indent to the craspedodrome bridge in grouping bridge and grouping tunnel with the craspedodrome tunnel; Arcuate structure has prolonged right-hand bend bridge length; Thereby reduced the right-hand bend bridge and will take very large-area problem at the parting of the ways because of the bridge length that the gradient needs; Make the distance between the diagonal building of crossroad only need more than 55 meters; Just can satisfy the needs of right-hand bend bridge, also just can satisfy the utility model group and take the little needs in ground and space.This just require two of opposite face in the same way two craspedodrome arch bridges of bifurcated " Y " font fork bridge rightabout driving separate, need not same bridge; And vertical dislocation is arranged; Promptly the ground upper bridge section of a straight bridge earth terminal of the lower bridge section of a craspedodrome arch bridge and a craspedodrome arch bridge of opposite rises jointly and between the bridge earth terminal spacing distance is arranged and not in same position; The straight bridge earth terminal of the lower bridge section of craspedodrome arch bridge is more near the center, crossroad; Straight bridge earth terminal if before near the zone, high position, stage casing of opposite craspedodrome arch bridge ground plane; Just abdicate the superjacent air space on right side, promptly let the right-hand bend bridge on opposite directly go out right curved bridge single file section, the multilevel traffic in addition the ground by-path at the parting of the ways of the right-hand bend bridge of realizing craspedodrome arch bridge and opposite at the side bifurcated of turning right for opposite craspedodrome arch bridge.As long as there is bridge section under the part of two straight bridge single file sections in the grouping bridge to be positioned at the opposite in the same way among the branch prong of bifurcated " Y " font fork bridge; Cheng Zhiqiao single file section partly descend the bridge section embed the opposite in the same way bifurcated " Y " font fork bridge divide the structure among the prong; But straight bridge single file section is not passed the right curved bridge single file section in opposite, makes the structure that does not have straight bridge single file section below the curved bridge single file section in the right side of this position and be one deck pontic.

Craspedodrome arch bridge 2 is the current bridges of two ground by-paths that are used for the crossroad opposite face; Craspedodrome tunnel 22 is the current tunnels of two ground by-paths that are used for the crossroad opposite face; " craspedodrome " is meant that motor vehicles arrive the meaning of opposite, crossroad road; " craspedodrome " is not meant shape, and is meant purposes.

Right-hand bend bridge 3 is the right-hand bend bridges that are used for crossroad left lateral traffic system, and " right-hand bend " is that purposes is the meaning of turning right.Right-hand bend tunnel 23 is the right-hand bend tunnels that are used for crossroad left lateral traffic system, and " right-hand bend " is that purposes is the meaning of turning right.

The bifurcated section 7 of right-hand bend bridge 3 is the bridge sections that are used for passing from ground from the motor vehicles of the craspedodrome arch bridge 2 on opposite current usefulness; There are motor vehicles to pass the height of needs below the height of bifurcated section 7 need satisfy, are preferably in zone, the high position bifurcated that satisfies traffic specification with craspedodrome arch bridge 2 so the right-hand bend bridge 3 of bridge 1 pitched in same bifurcated in the same way " Y " font.The bifurcated section 27 in right-hand bend tunnel 23 is the tunnel construction sections that are used for striding across from ground from the motor vehicles in the craspedodrome tunnel 22 on opposite current usefulness; The degree of depth that the current needs of motor vehicles are arranged above the degree of depth of bifurcated section 27 need satisfy is put regional bifurcated so the right-hand bend tunnel 23 in same bifurcated in the same way " Y " font fork tunnel 21 is preferably in the deep-seated that satisfies traffic specification with craspedodrome tunnel 22.

Right-hand rotation bridge earth terminal 6 preferably is positioned near the ground the bifurcation 35 in bifurcated in the same way " Y " font fork tunnel 21 of the ground by-path that right-hand bend will arrive; Right curved bridge single file section 13 does not stride across bifurcated in the same way " Y " the font fork tunnel 21 of the ground by-path that right-hand bend will arrive, so that the right-hand bend motor vehicles stride across bifurcated in the same way " Y " the font fork tunnel 21 of the ground by-path that is arrived from ground.The right-hand bend motor vehicles are gone up the through vehicles merging track of arriving ground in bifurcated " Y " the font fork 21 craspedodrome tunnels 22, tunnel in the same way on ground and left side, long ground, merging track section can be arranged, rather than have only one to merge the track point.Avoided the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge; Make the through vehicles on right-hand bend vehicle and ground, the left side by-path merge the track, be easy to generate the problem of traffic congestion but the merging track point on bridge is too narrow very little in the pontic position of two bridges.

Right-hand rotation tunnel earth terminal 26 preferably is positioned near the ground the bifurcation 15 of bifurcated in the same way " Y " font fork bridge 1 of the ground by-path that right-hand bend will arrive; Right curved tunnel single file section 33 is not passed bifurcated in the same way " Y " the font fork bridge 1 of the ground by-path that right-hand bend will arrive, so that the right-hand bend motor vehicles pass bifurcated in the same way " Y " the font fork bridge 1 of the ground by-path that is arrived from ground.The right-hand bend motor vehicles in ground and left side in the same way 2 times through vehicles of bifurcated " Y " font fork bridge 1 craspedodrome arch bridge to ground merge tracks, long ground, merging track section can be arranged, rather than have only one to merge the track point.It is too narrow very little and be easy to generate the problem of traffic congestion to have avoided merging track point.

The stage casing of bifurcated " Y " font fork bridge 1 is provided with the zone, high position in the same way; So that from the left side in the same way the right-hand bend vehicle in bifurcated " Y " font fork tunnel 21 earth terminal 26 passes below it behind ground from the right-hand rotation tunnel, bifurcated " Y " font fork bridge 1 can multilevel traffic with the right-hand bend vehicle from the left side in the same way thereby realize this.The stage casing in bifurcated " Y " font fork tunnel 21 is provided with deep-seated and puts the zone in the same way; So that from the left side in the same way the right-hand bend vehicle of bifurcated " Y " font fork bridge 1 from right-hand rotation bridge earth terminal 6 to ground after from it face stride across, bifurcated " Y " font fork tunnel 21 can multilevel traffic with the right-hand bend vehicle from the left side in the same way thereby realize this.

Grouping bridge is by minute prong relative two combining structure of bifurcated " Y " font fork bridge 1 in the same way, and the straightgoing vehicle that goes as the rightabout of two ground by-paths of crossroad opposite face is realized keeping straight on and the right-hand bend car is realized the composite bridge of turning right.The grouping tunnel is by minute prong relative two combining structure in bifurcated " Y " font fork tunnel 21 in the same way, and the straightgoing vehicle that goes as the rightabout of two ground by-paths of crossroad opposite face is realized keeping straight on and the right-hand bend car is realized the combination tunnel of turning right.A crossroad needs the straight bridge single file section 8 of a grouping bridge and 28 one-tenth three-dimensional decussate textures of straight tunnel single file section in a grouping tunnel.

" cross " meaning of straight bridge single file section 8 and straight 28 one-tenth three-dimensional decussate textures of tunnel single file section does not limit and is an angle of 90 degrees intersection mutually; Here " cross " is identical with " cross " implication of crossroad; Promptly there is intersection in two roads of " cross " general reference, do not limit intersecting angle.So, if straight bridge single file section 8 has bending also still to be regarded as decussate texture with straight tunnel single file section 28.The shape of stereo cross shape structure is meant above decussate texture overlooks; Straight bridge single file section 8 and straight 28 one-tenth three-dimensional decussate textures of tunnel single file section; But straight bridge single file section 8 is not connected with straight tunnel single file section 28, space length is up and down arranged, and it is current to satisfy motor vehicles.

The optimum position of straight bridge earth terminal 5: the straight bridge earth terminal 5 of two embedded grouping bridges is near the opposite bifurcated section 7 below ground locations of bifurcated " Y " font fork bridge 1 in the same way.As long as make its through vehicles pass bifurcated section 7 from ground, then the height of bifurcated section 7 can reduce as far as possible, promptly the height of one deck bridge.The optimum position of straight tunnel earth terminal 25: the straight tunnel earth terminal 25 in two embedded groupings tunnel is near the opposite bifurcated section 27 top ground locations in bifurcated " Y " font fork tunnel 21 in the same way.Make its through vehicles stride across bifurcated section 27 from ground, then the degree of depth of bifurcated section 27 can reduce as far as possible.

The preferred structure of right-hand bend bridge 3: the curved bridge single file section 13 in the right side of right-hand bend bridge 3 is preferably to the arcuate structure of 28 one-tenth three-dimensional decussate textures of two straight bridge single file sections 8 and two straight tunnel single file sections central area indent.The preferred structure in right-hand bend tunnel 23: curved tunnel, the right side in right-hand bend tunnel 23 single file section 33 is preferably to the arcuate structure of 8 one-tenth three-dimensional decussate textures of two straight tunnel single file sections 28 and two straight bridge single file sections central area indent.In order to prolong the length of right curved bridge single file section 13 and right curved tunnel single file section 33; Meet the traffic specification requirement and satisfy the gradient; And take ground, crossroad, space, underground position less as far as possible, and the arcuate structure that the curved bridge single file section 13 in the right side and the turn fractions of right curved tunnel single file section 33 are arranged to concave.This preferred structure makes the utility model can be used for having only more than 55 meters between place, diagonal angle, the crossroad building, and the small-sized crossroad of two-way six-lane, can both build the unimpeded facility of combination of the utility model.This just makes the utility model can be used for the crossroad, arterial highway in old city, realizes that old arterial street crossroad straightgoing vehicle and right-hand rotation car that people hope have no road occupying unimpeded.

The curved bridge single file section 13 in the right side of arc of concaving designs with right curved tunnel single file section 33 min. turning radius: the central point with 28 one-tenth three-dimensional decussate textures of two straight bridge single file sections 8 and two straight tunnel single file sections is the center; Right curved bridge single file section 13 is the arcs to stereo cross shape structure centre indent, and right curved tunnel single file section 33 is the arcs to stereo cross shape structure centre indent; The curved bridge single file section 13 in the relative right side is L with the beeline length of right curved tunnel single file section 33; The min. turning radius of right curved bridge single file section 13 of arc or the right curved tunnel of arc single file section 33 is R; In the scope of 30.0 meters≤L≤80.0 meter, the relationship of L and R is: R=L ÷ 4+8.When L=60.0 rice, R=23.0 rice.L is long more, explains that the crossroad area is big more, and then turning radius R can be big more, and the right curved bridge single file section 13 of arc can be born the fast more travel speed of motor vehicle with the right curved tunnel of arc single file section 33.

At the parting of the ways, because there is not intersection road occupying collision problem between the motor vehicles in the left-hand bend of left lateral system, not the subject matter that this patent will solve so turn left.Turning left from ground can be without overpass bridge and tunnel, but will have the road occupying of intersection to conflict with bicycle and pedestrian.For avoiding this intersection road occupying conflict; Can be that the right side is widened with the outside in right-hand bend bridge 3 and right-hand bend tunnel 23; The left turning vehicle that is used for ground, right side by-path uses, and the bridge 3 of just turning right becomes the right-hand bend car of this ground by-path and the common combined bridge or the tunnel that uses of left turning vehicle of ground, right side by-path with right-hand bend tunnel 23.The structure in right-hand bend bridge 3 and right-hand bend tunnel 23 has no variation; Just become the right side, left-hand rotation combined bridge or the right side, the dual-purpose tunnel of left-hand rotation; It is unimpeded fully to make the utility model become four craspedodrome roads of crossroad, four right-hand rotation bends, four left-turning pathways; The full intercommunication combined type means of transportation of neither one intersection road occupying conflict point have promptly been realized the full intercommunication multilevel traffic facility that whole tracks, crossroad are unimpeded.But the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge will reach the unimpeded multilevel traffic in whole tracks, crossroad, is provided with the left-hand bend service bridge, and promptly turn left bridge and right-hand bend bridge are two graded crossing bridges side by side.According to overpass bridge and Tunnel Design standard; The minimum widith in the right side of the utility model, left-hand rotation combined bridge or tunnel can be 10.0 meters, but the left-hand bend bridge of the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge and right-hand bend bridge minimum widith side by side are 15.0 meters.Consequently, right, the left-hand rotation of one-sided realization, the utility model has reduced by 5.0 meters occupation of land width; Only this has reduced by 10.0 meters occupation of land face width degree with regard to one than the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge.This stand out of 10.0 meters; Make the combined type means of transportation of the utility model can be used for the almost crossroad of any two-way six-lane, and have the crossroad of a lot of two-way six-lanes all can not use the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge.That is to say; Make the combined type means of transportation of the utility model usability widely arranged than the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge; The combined type means of transportation of the utility model can be solved outside any problem of the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge, can also solve the multilevel traffic problem of the indeterminable littler crossroad of Chinese patent 200820230509.5 Figure of description disclosed screen frame shape overpass bridge.

" right side " " left side " in the described the right of the utility model or the left side, the right side or the left side, left side, right side is meant that the people stands in common bridge earth terminal 4 positions of rising of some bifurcateds in the same way " Y " font fork bridge 1; Or certain " Y " font fork tunnel 21 enter tunnel earth terminal 24 positions jointly, in the face of two straight bridge single file sections 8 of two " Y " fonts fork bridges 1 are gone judgement " right side " or " left side " with the stereo cross shape structure centre that two straight tunnel single file sections 28 in two " Y " font fork tunnels 21 are formed.

Described two bridges of the utility model section 14 and two tunnels side by side sections 34 comprise two tracks side by side at least.

The advantage of the utility model:

One, is divided into large communications facility the combination of four small-sized means of transportation; Reduce the disaster degree that geology changes: the disclosed screen frame shape of the Figure of description overpass bridge of Chinese patent 200820230509.5 " direct left and right commentaries on classics interchange overpass " is the large-scale screen frame formula of an integral body overpass bridge that is connected as a single entity; Total length is very long; Floor space is very big, when in total length and floor space, there being geology to change, will producing this overpass bridge and destroy; Cause whole large-scale overpass bridge not use, this crossroad access is paralysed fully.And the utility model to be split as bifurcated in the same way " Y " the font fork bridge that two independences are not connected to above-mentioned whole large-scale overpass bridge be small-sized overpass bridge; Bifurcated in the same way " Y " the font fork tunnel that is not connected with two independences is a minitunnel; Accomplish the right-hand rotation of four roads in crossroad and the unimpeded function of keeping straight on respectively with these two small-sized overpass bridges and two minitunnels; Want under the condition in identical driving speed per hour, identical technology ginsengs such as the pontic gradient; Compare the large-scale screen frame overpass bridge of Chinese patent 200820230509.5 Figure of description; Small-sized overpass bridge of each of the utility model and the total length shortening 30-35% of each minitunnel than present large-scale overpass bridge, two small-sized overpass bridges and two minitunnel gross areas reduce 30-50%; Basically do not take the ground beyond the road self, and the underground and aboveground space on this ground; Just the utility model has reduced the degree that local damage damages integral body greatly; Reduced geology so greatly and changed the economic loss that causes damage, also can make the traffic of crossroad can not accomplish paralysis; In a word, the utility model is with the risk that greatly reduces geological disaster.

Two, turn right and turn left shared right-hand bend bridge or right-hand bend tunnel: right-hand rotation bridge earth terminal or right-hand bend tunnel earth terminal are connected with the left turn lane of ground, right side by-path, just can be used as the shared bridge of left turning vehicle or the shared tunnel of ground, right side by-path.The minimum widith in shared bridge or tunnel will reduce by 5.0 meters right left sides than the overall width of two independent bridges or two separate tunnel.The right-hand rotation bridge of the disclosed screen frame shape of the Figure of description of Chinese patent 200820230509.5 overpass bridge and left-hand rotation bridge are two independent bridges all.So whole composite bridge of the utility model or combination tunnel have reduced than the disclosed screen frame shape of Chinese patent 200820230509.5 Figure of description overpass bridge and have taken the ground circular diameter more than 10.0 meters.Then the utility model can be used for littler crossroad, and is spendable wider.

Three, the vehicle that leaves the crossroad has the ground of broad as merging the track section: two small-sized overpass bridges; Be not connected with two minitunnels are independent; Can arrive ground away from the vehicle of crossroad and merge the track with the vehicle that other leaves the crossroad on ground again, and not on bridge or in the tunnel, merge the track.Merging the track on ground can have very wide very long merging track section, is difficult for blocking up because of merging the track.Avoided the disclosed screen frame shape of the Figure of description overpass bridge of Chinese patent 200820230509.5 on pontic, to merge the too little too narrow and traffic congestion problem that causes of lane position.

Four, be same as the former circuit of plane traffic basically and do not have unnecessary detouring: it is unimpeded that two-way six-lane crossroad craspedodrome motorway and the motor-driven road of right-hand bend car are had no road occupying, and solved the traffic congestion that produces because of the two road usual friendship at the parting of the ways, problem blocks the traffic.This is a kind of unnecessary circuit that detours that do not have; Motor vehicles only have ascents and descents to be different from the plane traffic at the parting of the ways; And driving route is same as the driving route on the existing surface road that traffic lights are arranged basically, does not change direction of traffic and the custom of people in the usual friendship crossroad, gets lost because of unnecessary detouring in can current process at the parting of the ways; The engineering quantity of building bridge in addition is less than existing any intercommunicated overpass, practices thrift the bridge construction engineering cost.

Five, the little crossroad of two-way six-lane can be used: the utility model is only used two, and " Y " font Y-shaped arch bridge and two are combined into the means of transportation of crossroad in bifurcated " Y " font fork tunnel in the same way in the same way; It is unimpeded fully just to have realized that the crossroad has no road occupying and conflicts; Than the existing intercommunicated overpass that detours; Reduced the length of bridge in a large number with the disclosed screen frame shape of the Figure of description of Chinese patent 200820230509.5 overpass bridge; Reduced floor space in a large number, make its at the parting of the ways ground and space round diameter have only 55 meters two-way six-lane small size crossroad, city can realize that also grade separation is unimpeded, promptly do not intersect the road occupying conflict point; Also the section of interweaving not provides new design scheme for solving the global arterial street automobile traffic problem of blocking up.

Six, only use one deck bridge: one deck overpass bridge is only used on ground.Littler to the civic landscape influence.

Seven, human and vehicle shunting is realized on ground at the parting of the ways; Also the road is in the people: in the crossroad of using this patent facility; All operations under on the bridge or tunnel of motor vehicle; Do not have motor vehicle on the ground, so ground at the parting of the ways can supply pedestrian and non motorized vehicle to have free passage, realized that people's car separates, goes back in the traffic line of the hommization of the people.

Eight, more miniaturization of ground overpass bridge: the crossroad of using the utility model means of transportation; The all traffic from overpass bridge or the tunnel of craspedodrome motor vehicles and right-hand bend motor vehicles; Do not have motor vehicles current, have only pedestrian and non motorized vehicle current from ground, crossroad from ground, crossroad.Then the overpass bridge on ground only needs 2.5-3.0 rice headway just can satisfy the current requirement of pedestrian and non motorized vehicle at the parting of the ways.2.5-3.0 the overpass bridge of rice headway reduces 1.5-2.0 rice headway than 4.5 meters headway overpass bridges of current motor vehicle; Can reduce the 30%-40% headway; Then just can reduce the pontic length of 30%-40%; As long as the total length of " Y " font Y-shaped arch bridge is 380 meters right left sides in the same way to make two of the utility model, and this makes the overpass bridge of the utility model can not produce two too short and out of use problems of the road between the crossroad.

The inventive point of the utility model is:

One, establish same number, identical, discrete two small-sized " Y " the font overpass bridges of bifurcated direction and two small-sized " Y " font tunnels by the bar number of ground, crossroad by-path: the disclosed screen frame shape of the Figure of description overpass bridge of Chinese patent 200820230509.5 " direct left and right commentaries on classics interchange overpass " is the large-scale screen frame formula of an integral body overpass bridge that is connected as a single entity, and connects as one the whole three-dimensional bridge of the various runways in crossroad.And the utility model with prong facing each other two in the same way bifurcated " Y " font fork bridge form a composite bridge; With prong facing each other two in the same way bifurcated " Y " font fork tunnel form a combination tunnel; Composite bridge on the ground face both become three-dimensional criss-cross construction below ground in the tunnel with combination, do not take the ground beyond the road self, and the underground and aboveground space on this ground; Make the multilevel traffic fully respectively of bridge and tunnel, have no the road occupying of intersection point.The means of transportation miniaturization is not connected; Can reduce qualitative changeization partly and damage, make the small-sized crossroad of two-way six-lane the aspect such as can use, all be superior to the disclosed screen frame formula of the Figure of description overpass bridge of Chinese patent 200820230509.5 " direct left and right commentaries on classics interchange overpass " the means of transportation of whole crossroad.That is to say: from single comparison, the utility model is split as two small-sized " Y " font overpass bridges and two small-sized " Y " font tunnels to screen frame formula overpass bridge; From integral body relatively, the combination means of transportation in two small-sized " Y " font overpass bridges and two small-sized " Y " font tunnels become the little cross of floor space, rather than the wide screen frame shape of floor space.

Two, move on to traffic conflict point away from the by-path position of crossroad and go multilevel traffic: the utility model is not the position that the road occupying conflict takes place to intersect traffic behavior on the plane; The i.e. position in the scope at the parting of the ways not; Solution is from the direct lane and the right-turn lane of Different Ground by-path; And the conflict of the intersection road occupying between the right-turn lane; But creationaryly move on to these two types of traffic conflict points away from multilevel traffic transport solution conflict on four ground by-paths of crossroad, thereby can take the ground and the space of crossroad minimumly.The utility model requires to reduce greatly to the annular region floor area of crossroad.The means of transportation that the utility model just can be built up in ground and the space of crossroad diameter more than 55 meters realize that the crossroad access of old city six-lane is unimpeded, stop up initiative meaning is arranged for solving the little crossroad access in old urban area.

Three, on the by-path of the ground on two opposites, the ground of craspedodrome bridge prolongs the right-hand bend bridge of wearing the opposite under the track: keeping straight on relatively is two two-way craspedodrome arch bridges that rightabout is kept straight on, separate, not shared bridge; Be straight bridge earth terminal than the opposite in the same way bifurcated " Y " font fork bridge common play the bridge earth terminal more becomes three-dimensional decussate texture near two straight tunnels of two straight bridge single file sections and grouping tunnels of grouping bridge single file section center; Straight bridge earth terminal is near opposite ground connection before the zone, high position of bifurcated " Y " font fork bridge in the same way; So straight bridge earth terminal has been reserved the opposite high position section rightward space of bifurcated " Y " font fork bridge in the same way; Let the curved bridge single file section in the right side on opposite can be directly at the craspedodrome arch bridge bifurcated on right-hand bend one side and opposite; Two bridge bifurcateds can directly be turned right the right-hand bend vehicle and are not needed unnecessary detouring; The vehicle that leaves straight bridge earth terminal can be passed from the turn right ground, bifurcated section below of bridge of opposite face, realize the multilevel traffic of through vehicles and opposite right-hand bend vehicle, and have only the height of one deck bridge.

Four, under the by-path of the ground on two opposites, the ground in craspedodrome tunnel prolongs the right-hand bend tunnel that the track strides across the opposite: keeping straight on relatively is two two-way craspedodrome tunnels that rightabout is kept straight on, separate, not shared tunnel; Be straight tunnel earth terminal than the opposite in the same way bifurcated " Y " font fork tunnel enter the tunnel earth terminal more becomes three-dimensional decussate texture near two straight tunnels of two straight bridge single file sections and grouping tunnels of grouping bridge single file section center jointly; Straight tunnel earth terminal near the opposite in the same way the deep-seated in bifurcated " Y " font fork tunnel put regional ground connection; So straight tunnel earth terminal reserved the opposite in the same way the deep-seated in bifurcated " Y " font fork tunnel put the section rightward space; Let curved tunnel, the right side single file section on opposite can be directly at the craspedodrome tunnel bifurcated on right-hand bend one side and opposite; Two tunnel bifurcateds can directly be turned right the right-hand bend vehicle and are not needed unnecessary detouring; The vehicle that leaves straight tunnel earth terminal can be striden across from the turn right ground, bifurcated section top in tunnel of opposite face, realize the multilevel traffic of through vehicles and opposite right-hand bend vehicle, and need only the degree of depth in one deck tunnel.

Five, the ground of right-hand bend bridge prolongs craspedodrome bridge and the right-hand bend bridge of wearing ground, right side by-path under the track: the right bridge single file section of bending directly arrives near the ground connection in zone, high position near bifurcated in the same way " Y " the font fork bridge on right side by the right-hand bend direction; Its ground prolongs track and this high position zone multilevel traffic of bifurcated " Y " font fork bridge in the same way, just solved the ground by-path that right-hand bend vehicle and right-hand bend will arrive straightgoing vehicle and right-hand bend car intersect the road occupying collision problem.The right-hand bend vehicle does not detour, and has reduced unnecessary traffic conflict point.

Six, the ground in right-hand bend tunnel prolongs craspedodrome tunnel and the right-hand bend tunnel that the track strides across ground, right side by-path: the right tunnel single file section of bending is put near the ground plane in zone by the direct arrival of right-hand bend direction near the deep-seated in bifurcated in the same way " Y " the font fork tunnel on right side; Its ground prolong track with this in the same way the deep-seated in bifurcated " Y " font fork tunnel put regional multilevel traffic, just solved the ground by-path that right-hand bend vehicle and right-hand bend will arrive straightgoing vehicle and right-hand bend car intersect the road occupying collision problem.The right-hand bend vehicle does not detour, and has reduced unnecessary traffic conflict point.

Seven, be designed to the right side, left-hand bend combined bridge to the right-hand bend bridge: do not pass the right-hand bend bridge and do not stride across right side bifurcated " Y " font fork bridge in the same way; And right-hand rotation bridge earth terminal can be communicated with the left turn lane of ground, right side by-path, and the right-hand bend bridge just becomes the right side, left-hand bend combined bridge.And do not need two bridges respectively as right, the use of turning left.

Eight, the right-hand bend Tunnel Design become right, dual-purpose tunnel turns left: do not pass the right-hand bend tunnel and do not stride across bifurcated " Y " word jag tunnel in the same way, right side; And right-hand bend tunnel earth terminal can be communicated with the left turn lane of ground, right side by-path, and the right-hand bend tunnel just becomes the right side, dual-purpose tunnel turns left.And do not need two tunnels respectively as right, the use of turning left.
